As long as we play soft coverage / bend / don't break, I say just get some Average Joe or keep what we have. Then I'd go Top Of The Class across the board on O line. Because the current system puts a helluva lot of pressure on the O to score and not only be leading late in the 4th but by MORE than one TD and 2 point Conversion. Our scheme on D has even tied AD's hands. Hell, we could have another Fearsome Foursome but it doesn't mean Jack if QBs are getting rid of the ball in hardly two seconds to Receivers that have LOTS of room to run underneath and then met by a Secondary that cannot or will not (Observers) tackle worth a crap.
